Last updated: July 1, 2020.

Comparing Samsung Galaxy S3 and Galaxy S2

Samsung officially unveiled the Galaxy S3 yesterday at the Samsung Unpacked event held in London. Some people say that the Galaxy S3 is just a minor update to the Galaxy S2. But some claim it is a legitimate “next step” for the Galaxy line of smartphones.

Galaxy S2

In our review, we look at the Samsung Galaxy S3 and compare it to the Samsung Galaxy S2 to figure out if it is a real successor or just a minor upgrade.

Display and design

  • The Samsung Galaxy S3 has a 4.8 inch SAMOLED HD display
  • On the other hand, the Samsung Galaxy S2 has a 4.3 inch Super AMOLED Plus display.
  • The Galaxy S3 has a display resolution of 1280 x 720 pixels
  • Moreover, the Galaxy S2 has a display resolution of 480 x 800 pixels
  • The S3 uses the PenTile pixel arrangement
  • The S2 uses an RGB matrix arrangement
  • While the use of PenTile doesn’t mean that the display of the S3 is poor, it doesn’t achieve its 306 PPI pixel density naturally
  • The colors are vivid and the contrast great, so in this sense, it is a step up from the S2 display
  • Both the Samsung Galaxy S3 and the Samsung Galaxy S2 use Corning Gorilla Glass to protect their screens from scratches
  • Because the Galaxy S3 has increased the display size by half an inch, the handset has increased as well
  • The increase is not that big as they made the bezels smaller but it’s still a marked difference from the Galaxy S2
  • The Samsung Galaxy S3’s measurements are 136.6 x 70.6 mm while the S2 is 125.3 x 66.1
  • Meanwhile, the Samsung Galaxy S3 is also a bit thicker than the Samsung Galaxy S2
  • The Galaxy S3 is 0.1 mm thicker than the Galaxy S2
  • For weight, the Galaxy S3 is also heavier, weighing 133 grams


Processor, GPU, and RAM

  • On the processor side, the Samsung Galaxy S3 has a quad-core Exynos 4212 processor which clocks at 1.4 GHz per core
  • The Exynos 4212 is manufactured by Samsung but based on ARM Cortex A9
  • Moreover, the Exynos 4212’s initial benchmark results place it as faster than the dual-core Snapdragon S4 as well as the quad-core Nvidia Tegra 3
  • The Samsung Galaxy S2 has a dual-core Exynos processor clocked at 1.2 GHz
  • The processor in the Galaxy S2 is also based on Cortex A9
  • For the GPU, the Galaxy S3 and the Galaxy S2 have the same GPU architecture
  • The Galaxy S3 and the Galaxy S2 use a Mali-400 MP
  • The two do differ in speed, though, with the Galaxy S3’s GPU clocked at 400 MHz and the Galaxy S2’s clocking at 233 MHz
  • Both the S3 and the S2 have 1 GB of RAM.

LTE Connectivity

  • Samsung has stated that the Samsung Galaxy S3 is going to be available with LTE versions
  • However, they didn’t specify if the 3G and LTE versions of the Samsung Galaxy S3 would be different
  • Some believe that the US-based LTE versions of the Samsung Galaxy S3 will use a Qualcomm Snapdragon S4 processor
  • Nevertheless, Samsung equipped the Samsung Galaxy S2 LTE version with a Qualcomm Scorpion CPU and this could affect their decision with the Samsung Galaxy S3
  • If we’re lucky the LTE version of the Galaxy S3 will have an Exynos 4212 processor.


Camera, Storage, and Battery

  • For camera, The Samsung Galaxy S3 has the same 8 MP that is found in the Samsung Galaxy S2
  • While some might find it disappointing that Samsung didn’t bother upgrading cameras, the Galaxy S2 camera has proven itself to be a good device. It can takes great photos as well as 720 p and 1080 p videos
  • Moreover, the Samsung Galaxy S2 only offered 16 GB and 32 GB storage options
  • While, the Samsung Galaxy S3 offers those two and adds a 64 GB variant for storage space
  • Both the Galaxy S3 and the Galaxy S2 have a microSD card slot so you can expand your storage space as needed.
  • Galaxy S3 users will also be able to take advantage of an offer for a free DropBox cloud storage account with 50GB
  • For battery, the Samsung Galaxy S3 is a 2,100 mAh
  • The battery of the Samsung Galaxy S2 is a 1,650 mAh
  • While the Galaxy S3 has the bigger battery, we are as yet unsure as to how much of this will end up going to power the Galaxy S3’s bigger display and the quad-core processor
  • While we are not sure how much power the Galaxy S3’s display and the processor will end up consuming. We really don’t expect the Galaxy S3’s bigger batter to mean that it will have a longer battery life than the Galaxy S2.



The Samsung Galaxy S3 really sounds like a device that will be known as one of the world’s best Android Smartphones. The Galaxy S3 has the fastest processor available, a great design, and will run the latest version of Android, the Android 4.0 Ice Cream Sandwich. The Galaxy S3 beats the Galaxy S2 in almost every way and is a great and true successor. It turned out to be the best-selling Android Smartphone in 2011.

While we love the Galaxy S3, we can’t deny that there will be many who will express disappointment. It’s about that Samsung used PenTile arrangement and not RGB Matrix. If the S3 has an SAMOLED HD Plus screen, it would be everything and Android user could hope for.

What do you think? Will you upgrade to the Galaxy S3? Or stick to the Galaxy S2?
